Which home inspection findings are actually serious?

Four categories: structural movement (foundation cracks with displacement, sagging framing), active water intrusion, failing major systems (knob-and-tube wiring, undersized panels, failed sewer lines), and anything hiding behind finishes that the inspector could not see. Cosmetic findings and normal wear fill most of the report and matter far less.

What do common inspection repairs cost in the Seattle area?

Rough 2026 ranges: electrical panel replacement $3,000–$6,000, whole-house rewire $15,000–$40,000, sewer line replacement $8,000–$25,000, foundation repair $5,000–$40,000+ depending on cause, and roof replacement $15,000–$40,000. Water damage is the true variable — it depends entirely on what the water reached.

Should a contractor look at a house before I buy it?

If you plan to remodel it, yes. An inspector tells you the condition; a builder tells you what changing it costs. Knowing before closing whether the wall you want removed is structural, or whether the panel supports the kitchen you want, changes what the house is worth to you.

Can I negotiate repairs into the price?

Often, though it depends on the market. What strengthens your position is specificity: a written contractor estimate for the actual scope is far more persuasive than a line item in an inspection report. It also tells you your real all-in number.

Your Home Inspection Found Problems. What Do They Cost to Fix?

A builder's read on inspection reports: which findings are serious, which are noise, real Seattle-area repair costs, and how to fold them into a remodel budget before you buy.

An inspection report is a list of observations, not a bill. It tells you what is wrong and almost never what fixing it costs — which is why the reaction to a forty-page report is usually panic. Here is how a builder reads one, and what the findings actually run around Seattle.

The four findings that genuinely matter

Structural movement. Foundation cracks with displacement, sloping floors, sagging ridge lines. Sometimes decades-old and stable; sometimes active. This is the one finding worth paying an engineer to characterize before you close.
Active water. Anything wet now — roof leaks, failed flashing, a chronically damp crawl space. Water is what turns a small repair into a structural one, and in this climate it never pauses.
Failing systems. Knob-and-tube wiring, a 60-amp panel, galvanized supply lines, a sewer line at the end of its life. Common in the 1905–1965 stock we work in across Seattle, and expensive to ignore.
“Not accessible.” The most important phrase in any report. An inspector cannot open walls. Whatever they could not see is exactly what a remodel will find — which is why the 10–15% contingency is not optional in an older house.

Rough Seattle-area repair costs

Electrical panel replacement: $3,000–$6,000
Whole-house rewire: $15,000–$40,000
Sewer line replacement: $8,000–$25,000
Foundation repair: $5,000–$40,000+ by cause
Roof replacement: $15,000–$40,000
Water damage: entirely dependent on reach

Ranges, not quotes — the honest number needs eyes on the house.

The move most buyers miss

If you are buying a house you intend to remodel, get a builder in during the inspection period alongside the inspector. The inspector documents condition; the builder prices change. Knowing before you close whether the wall between the kitchen and dining room is load-bearing, whether the panel supports the kitchen you have in mind, and what the whole plan costs is the difference between a budget and a hope.

The silver lining in a bad report

A house needing systems work is a house where remodeling is efficient: the walls have to open anyway. Replacing wiring and plumbing during a whole-home remodel costs a fraction of doing it as a standalone project later. Findings that scare other buyers can be exactly why the house is the right buy for someone planning to renovate.
